Patterns for building High Performance Applications

Reduce Latency

Scalability

High Availability

Application requirements

5

Scalability

No Load Balancing vs Load Balanced

Stateful vs Stateless

Synchronous vs Asynchronous

6

Reduce Latency

ESB

SOA

Simplify – Not too many moving parts, simple

application tiering

Bring data close to customer – Cache (browser, edge, webserver, data cache)

Host closer to Customer – choose Cloud Vendor wisely

7

Fail Over

Master - MasterMaster - Slave

Write

WriteRead

Read

Update

High Availability

Master - Master Replication mode

Master-Slave replications mode

High Performance Applications – Impact Factors

• Topology of the Solution

• Single Point of Failure(s)

• Chosen Product Stack

• Product Integration Strategy

Solution Architecture

• Application Design• Choice of

Frameworks• Standards

Enforcement• Build & Release

Application Architecture

• Hardware Choices made

• Hardware/Software Sizing

• System Configuration(s)

• Hosting Environment• Application/System

Monitoring• Capacity Planning

Deployment Architecture

Reduce Latency

Summary

• Patterns• Scalability

• Load Balancer• Asynchronous• Stateless

• Reducing Latency• Bring data closer to end user• Do not have too many moving parts• Host your application close to users!

• High Availability• Fail Over• Redundancy

You can read all the books in the world about riding a bicycle, but you will not be able to ride one until you

get on it and fall off a few times.
